I was thinking there of the potential of the scientific method to explain natural facts, as distinct from values. The economic or political use of science is another matter.

I agree that nature can tell us what to do in the sense that it presents us with our existential condition. But there's an open question as to how we should respond to those basic facts. Nature can provide us indirectly with certain technological abilities, but that doesn't entail that we ought to use them in certain ways or at all. The fact that solar power exists doesn't entail that we should use the Sun to power our societies. This is just a question of the naturalistic fallacy.
